*	op: refactor do handling.	Kaz Kylheku	2021-06-30	1	-19/+37
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	* stdlib/op.tl (op-expand): The logic involving the multiple expansions of do is consolidated into one step, so that everything is taken care of by the time syntax-1 is produced. Immediately when the initial unsuffixed arguments expand successfully, we check or the presence of metas and add the @1 if metas are absent. In the case of expanding with the gensym, we immediately replace that with @1 without using symacrolet. The do-gen variable is gone. Later, when calculating lambda-interior, there are no hacky additional passes to deal with; that block of code just refers to syntax-2. The do case is folded together with the have-metas case. Also adding copious comments to this hard-to-follow logic.
*	op: bug in do: must insert @1 into unexpanded form.	Kaz Kylheku	2021-06-29	1	-2/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	In the case when the do syntax has no metavariables, and it expands as-is without the addition of symbol in the tail position, we are doing something wrong: we are adding the @1 into the expanded version of the form, rather than the original. For instance: 1> (expand '(do pop a)) (lambda (#:arg-1-0017 . #:arg-rest-0016) (prog1 (car a) (sys:setq a (cdr a)) #:arg-1-0017)) Here, the @1 was inserted into the (prog1 ...) form which is the expansion of pop. This is incorrect; it must be inserted into the original (pop a) syntax as (pop a @1). * op.tl (op-expand): In this case when there are no metas and no do-gen that can be replaced by @1 via symacrolet, go back to the original args syntax, add the arg1 meta into that syntax, and process it from the beginning through parallel expansions steps. * tests/012/op.tl: Couple of tests added.
*	file layout: moving share/txr/stdlib to stdlib.	Kaz Kylheku	2021-06-24	1	-0/+203
	This affects run-time also. Txr installations where the executable is not in directory ending in ${bindir} will look for stdlib rather than share/txr/stdlib, relative to the determined installation directory. * txr.c (sysroot_init): If we detect relative to the short name, or fall back on the program directory, use stdlib rather than share/txr/stdlib as the stdlib_path. * INSTALL: Update some installation notes not to refer to share/txr/stdlib but stdlib. * Makefile (STDLIB_SRCS): Refer to stdlib, not share/txr/stdlib. (clean): In unconfigured mode, remove the old share/txr/stdlib entirely. Remove .tlo files from stdlib. (install): Install lib materials from stdlib. * txr.1: Updated documentation under Deployment Directory Structure. * share/txr/stdlib/{asm,awk,build,cadr}.tl: Renamed to stdlib/{asm,awk,build,cadr}.tl. * share/txr/stdlib/{compiler,conv,copy-file,debugger}.tl: Renamed to stdlib/{compiler,conv,copy-file,debugger}.tl. * share/txr/stdlib/{defset,doc-lookup,doc-syms,doloop}.tl: Renamed to stdlib/{defset,doc-lookup,doc-syms,doloop}.tl. * share/txr/stdlib/{each-prod,error,except,ffi}.tl: Renamed to stdlib/{each-prod,error,except,ffi}.tl. * share/txr/stdlib/{getopts,getput,hash,ifa}.tl: Renamed to stdlib/{getopts,getput,hash,ifa}.tl. * share/txr/stdlib/{keyparams,match,op,optimize}.tl: Renamed to stdlib/{keyparams,match,op,optimize}.tl. * share/txr/stdlib/{package,param,path-test,pic}.tl: Renamed to stdlib/{package,param,path-test,pic}.tl. * share/txr/stdlib/{place,pmac,quips,save-exe}.tl: Renamed to stdlib/{place,pmac,quips,save-exe}.tl. * share/txr/stdlib/{socket,stream-wrap,struct,tagbody}.tl: Renamed to stdlib/{socket,stream-wrap,struct,tagbody}.tl. * share/txr/stdlib/{termios,trace,txr-case,type}.tl: Renamed to stdlib/{termios,trace,txr-case,type}.tl. * share/txr/stdlib/{ver,vm-param,with-resources,with-stream}.tl: Renamed to stdlib/{ver,vm-param,with-resources,with-stream}.tl. * share/txr/stdlib/yield.tl: Renamed to stdlib/yield.tl. * share/txr/stdlib/{txr-case,ver}.txr: Renamed to stdlib/{txr-case,ver}.txr. * gencadr.txr: Update to stdlib/place.tl. * genman.txr: Update to stdlib/cadr.tl.
